Siemens SIMATIC ET 200SP Manual page 35

Requirements
Ensure the following states exist:
1. The CPU is in "STOP" state or the bus is disconnected from the IM module of the
ET 200SP.
2. The AS-i master and all AS-i slaves are connected to the AS-Interface and supplied with
voltage.
3. No AS-i slave with address 0 is connected to AS-Interface. The AS-i slaves have unique
addresses that differ from one another.
Procedure
1. Check whether the AS-i master is in "configuration mode". (The "CM" LED lights up.)
If the "CM" LED does not light up, switch the AS-i master to "configuration mode" by
pressing the "SET" button once.
2. Press the "SET" button. This configures the AS-i master. In so doing, the ACTUAL
configuration detected is saved as the CONF configuration in non-volatile memory in the
CM AS-i Master ST. At the same time, the AS-i master switches over to "protected
operation". The "CM" LED goes out.
Note
Parameter setting when configuring with the "SET" button
If no AS-i slaves are connected, all internal lists are set to default values. In particular, the
following are set: all AS-i parameters = F
When configuring is performed using the "SET" button, the parameter value in the volatile
memory of the AS-i master for each slave applied to the CONF configuration is saved as a
non-volatile parameter. For slaves that are not present, the default value F
non-volatile memory. This corresponds to the function of the No. 00:
Set_Permanent_Parameter (Page 107) command.
Note
The existing configuration can be overwritten using the "SET" button
Note regarding the CM AS-i Master ST:
A configuration of AS-i slaves specified using
transferred to the AS-i master again during S7 station start-up or after station recovery of the
head module. Any configuration implemented using the "SET" button will be overwritten.
When configuring with the "SET" button, if no slaves are connected to AS-Interface, the
CONFIGURED configuration in the master is deleted along with the profile definition for
proxy slaves (see Section "AS-i proxy slave (Page 42)"). The AS-i voltage must be present.
